LA ( Roller Cam ) prep

Good note I forgot about!
With my Hyd. Roller cammed 360 with Edelbrock heads and Comp roller rockers using 5/16 p-rods need some clearancing for the pushrods to clear. The pushrod holds in the head needed to be ovaled slightly on the intake side.
I'm using eddy heads as well with 1.6 rockers and even with 5/16" pushrods it didn't clear the tubes with out some drilling and grinding.
